Fusion items? It seems to be a synthetic object, right? Chladik's Rubik's Cube is a game prop, and the second act 1 played in the task 1 prop. If you have done this task, you should have synthesized Chladik's staff. You must have experienced it. I don't think you have. No need to modify it, just go back to the third act. According to the plot, you synthesized two props, and the other was Klimt's will. Well, it's probably what it looks like. You clean the inside of Chladik's Rubik's Cube without any other equipment, then put the items to be synthesized in it, and click Change to synthesize them. The premise is that there is this synthesis formula. You put three small purple medicines (plus 35% blood and magic) in the box first, and then you can synthesize a big purple (full reducing medicine, blood and magic). This formula is the simplest and most feasible. Go do an experiment and experience it. Anyway, synthesis is to put the equipment in, change it, and you can make a piece of equipment. If you can't use the synthesis formula, it may be that this formula doesn't match your version, or this formula has requirements (Battle.net, single machine, ladder difficulty, etc. ).
